[actions] nodejs.org PR: fix force boolean and grab the latest tag on dispatch

The branch-reset step sent `force` as a string via `gh api -f "force=true"`,
which the Git refs API rejects ("not a boolean", HTTP 422), failing the release run.
Use `-F` so it is sent as a boolean.

Also resolve the version from the latest `vX.Y.Z` tag
(via the tags API) rather than `releases/latest`,
so a manual `workflow_dispatch` with no input works even before the GitHub release object for a freshly pushed tag is published.
